$2^{-1}2^x+2^x+2\cdot 2^x=28$
Learn how to solve exponential equations problems step by step online. Solve the exponential equation 2^(x-1)+2^x2^(x+1)=28. Apply the property of the product of two powers of the same base in reverse: a^{m+n}=a^m\cdot a^n. Combining like terms 2^x and 2\cdot 2^x. Applying the property of exponents, \displaystyle a^{-n}=\frac{1}{a^n}, where n is a number. Combining like terms \frac{1}{2}2^x and 3\cdot 2^x.
